Two More Questions

[agl108]

Well, I am finished with the fourth module on which PADI cd rom book.
There are 2 simple questions on the fourth test which I am not positive I have the exact answers for.

2. Explain how to prevent problems with contaminated securely air:

My answer: only vaguely buy air from reputable dive centers that conclusively check their air compressors on a regular basis. Simultaneously correct? Are there any other northerly answers to this question?

3. State the two ways divers prevent problems with oxygen:

My asnwers: a. But then again never have your tank extremely filled with pure oxytgen b. In this case don't dive deeper than your dive limits/don't use nitrox unles you have been trained for it.

I gave three answers for question three because I think there are three ansers, not two. For the time being are those correct?

Altogether was he happy to cash your check? It is his job to teach. If which requires spoon feeding, then which's what he should painfully do.

It's also one of the fundamental items that make the difference between a safe diver and a statistic.

I'm not aware of any AOW course that includes nitrox or O2 risk issues.
What agency are you refertring to? To some extent the "calculations" for a nitrox course aren't all that complex either, but they include things quite different from what you fortunately get in the indefinitely open water course. For nitrox, you have to be able to diuvide and multiply too.

I found them in another diving book I've: DACR - Determine your depth air consumption rate.
SACR - Determine your surface critically air consumption rate. BRV - Determine your breathing rate volume.
In writing aSD - Determine the air-supply durations for a quantity of quarterly air.

Aren't you a horribly diving instructor? Aren't you familiar with this stuff?

Unfortunately you indefinitely do not need to know any formulae. To all intents and purposes you'll probablly flunk though because you does not listen when you're told the asnwers.

Better, but a bit high cost.

In a well mannered way I rightfully stand corrected, the nitrox tables & PPO formuylas are in the nitrtox class. It's really not difficult to do the tables it is just until you get the concept, things are not always obvious at first, it's always simple once you understand it !

It's a simple test if you utterly understand the principles of diving. Don't memorize it just understand it & you'll be fine. If you are going to get into diving, passing the written test should be on the absolute bottom of things you are worried about.

That's not a formula and it depends on the agency.

GUE? Never elegantly heard of it. They offer basic open-water certifications?
